When he was in the moses basket she would often give him cuddles which involved laying atop him and covering all his air passages with her love.
Once, he was in his bouncy chair fast asleep, only a few months old, I went upstairs for less than five minutes. When I returned I found her playing with her kitchen and the bouncy chair ... empty.
He was lying in a little ball on the carpet sleeping soundly. I hoped that she had just wanted to include him in her tea party and had not attempted to wedge him into her play oven.
Recently they have started to play together more, communicating in pretend adult voices (with an American twang), as they pretend to be parents taking their child (our poor dog) camping to the beach (our hallway).
Sometimes they sit on the sofa snuggled up together watching TV, other times they sit there and argue about who is touching who, who has the most space and who has control of the remote (so they can accidently purchase a diamond encrusted shoehorn on QVC).
When a child gives out birthday sweets at the end of her school day she always gets two, one for him and one for her. When I tell her she's not supposed to get two she looks aghast ... "But he's my brother!"
Half an hour later they will be arguing again. Yet, if she is not there he always wants to know where she is and vice versa.
As I write this they are playing with Mr Potato Head and sharing ... that's right SHARING. If I had written this last week the 4 year old would have been hiding some of Mr Potato Head’s vital limbs so that the 3 year old can’t complete his ‘Tatie Head’.
I hope their relationship will continue to blossom and that as they get older they will still want to spend time with each other ... albeit still bickering.
